Persistent supply chain disruptions and inflation pressures are constraining the global economy's recovery from the COVID-19 pandemic, the International Monetary Fund (IMF) said on Tuesday as it cut growth outlooks for the United States and other major industrial powers.

In its World Economic Outlook, the IMF trimmed its 2021 global growth forecast to 5.9% from the 6.0% forecast it made in July. It left a 2022 global growth forecast unchanged at 4.9%.

"This modest headline revision, however, masks large downgrades for some countries," the IMF said in the report, adding that worsening pandemic dynamics have darkened the outlook for low-income developing economies, while wealthy countries are struggling with supply disruptions.
